WEAK ACIDIC CATION EXCHANGE BODY AND MANUFACTURING METHOD THEREFOR, CATION EXCHANGE CHROMATOGRAPHY COLUMN, ANALYTICAL METHOD OF CATION

摘要

PROBLEM TO BE SOLVED: To provide a weak acidic cation exchange body capable of analyzing monovalent and bivalent cation at same time and maintaining holding ability of cation for long time.SOLUTION: There is provided a weak cation exchange body consisting of a reaction product by reacting a raw material containing a carrier (A), alkoxy silane having a double bond in a molecule (B), a compound having a carboxyl group or an acid anhydride group and an ethylenic double bond and no ester bond (C) and a radical initiator (D) and the reaction product has a part where the carrier (A) and the alkoxy silane (B) chemically bind (a) and a part where the double bond based on the alkoxy silane (B) and the double bond based on the compound (C) copolymerize (b).
